Question

我正在尝试将此c＃转换为具有webbrowser控件的vb.net，但我很困惑。代码在用户控件中。

C＃

 private void SetupEvents()
    {
        webBrowser1.Navigated += new WebBrowserNavigatedEventHandler(webBrowser1_Navigated);
        webBrowser1.GotFocus += new EventHandler(webBrowser1_GotFocus);
    }

 [Browsable(true)]
    public override Color BackColor
    {
        get
        {
            return base.BackColor;
        }
        set
        {
            base.BackColor = value;
            if (ReadyState == ReadyState.Complete)
            {
                SetBackgroundColor(value);
            }
        }
    }



public HtmlDocument Document
        {
            get { return webBrowser1.Document; }
        }

错误 '公共事件导航（发送者为对象，e为System.Windows.Forms.WebBrowserNavigatedEventArgs）'是一个事件，不能直接调用。使用'RaiseEvent'语句来引发事件。

请帮助

Answer 1

假设webBrowser1_Navigated和webBroswer1_GotFocus是同一个类中的方法，那么在SetupEvents（）方法中：

AddHandler WebBrowser1.Navigated, AddressOf webBrowser1_Navigated
AddHandler WebBrowser1.GotFocus, AddressOf webBrowser1_GotFocus

Answer 2

您必须使用AddHandler关键字而不是+ =来设置事件处理程序。

Answer 3

试试这段代码：

Private Sub SetupEvents()
    AddHandler webBrowser1.Navigated, AddressOf Me.webBrowser1_Navigated
    AddHandler webBrowser1.GotFocus, AddressOf Me.webBrowser1_GotFocus
End Sub    
<Browsable(true)>  _
Public Overrides Property BackColor As Color
    Get
        Return MyBase.BackColor
    End Get
    Set
        MyBase.BackColor = value
        If (ReadyState = ReadyState.Complete) Then
            SetBackgroundColor(value)
        End If
    End Set
End Property

Public ReadOnly Property Document As HtmlDocument
    Get
        Return webBrowser1.Document
    End Get
End Property

Private Sub SetupEvents()
    AddHandler webBrowser1.Navigated, AddressOf Me.webBrowser1_Navigated
    AddHandler webBrowser1.GotFocus, AddressOf Me.webBrowser1_GotFocus
End Sub

将c＃转换为vb.net webbrowser
